Coast
A coastline or seashore is the area where land meets the sea or ocean. A precise line that can be called a coastline cannot be determined due to the dynamic nature of tides. The term "coastal zone" can be used instead, which is a spatial zone where interaction of the sea and land processes occurs...

). The topography is characterized by rugged hills, and there are many freshwater and salt lakes. The largest and deepest lake, Algae Lake (Lake Figurnoye) is 25 km (16 mi) long and up to 137 metres (449 ft) deep. The leader of Operation Highjump, Admiral Richard E. Byrd stated that the Bunger Hills was ‘…one of the most remarkable regions on earth. An island suitable for life had been found in a universe of death.’

The Soviet Union became interested in the Bunger Hills again in the late 1980s, and built a new station - Oazis-2 - a few hundred metres to the west of Dobrowolski. The station was used for summer visits up to the mid-1990s.
